Journal ArticleDOI
The primordial environment of supermassive black holes (II): deep Y and J band images around the z=6.3 quasar SDSS J1030+0524
B. Balmaverde,Roberto Gilli,M. Mignoli,M. Bolzonella,Marcella Brusa,Nico Cappelluti,Andrea Comastri,E. Sani,Eros Vanzella,C. Vignali,F. Vito,G. Zamorani +11 more
TL;DR: In this article, the authors presented wide-area (25x25 arcmin), Y-and J-band imaging of the SDSSJ1030+0524 field obtained with the near infrared camera WIRCam at the Canada-France-Hawaii Telescope (CFHT).
Journal ArticleDOI

J. Oliver,Michael Rowan-Robinson,Gene Smith,C. Lonsdale +24 more
TL;DR: In this paper, a catalog of optical spectroscopic identifications of sources detected by Spitzer at 3.6 or 24 μm down to ~10 and 280 μJy, respectively, in the SWIRE/XMM-Newton/ELAIS-S1 field was presented.
Journal ArticleDOI
Hidden activity in high-redshift spheroidal galaxies from mid-infrared and X-ray observations in the GOODS-North field
Giulia Rodighiero,Carlotta Gruppioni,Francesca Civano,Francesca Civano,Andrea Comastri,Alberto Franceschini,M. Mignoli,Jacopo Fritz,Cristian Vignali,Tommaso Treu +9 more
TL;DR: In this paper, the authors exploit very deep mid-infrared (MIR) and X-ray observations by Spitzer and Chandra in the GOODS-North field to identify signs of hidden [either starburst or active galactic nucleus (AGN)] activity in spheroidal galaxies between z≃ 0.3 and 1.4 GHz.
Journal ArticleDOI
X-ray detected infrared excess AGN in the Chandra deep fields: a moderate fraction of Compton-thick sources
TL;DR: In this article, the properties of the X-ray-detected infrared excess AGN or dust obscured galaxies (DOGs) in the Chandra deep fields (CDFs) were examined.
Journal ArticleDOI

Bruce,Ricardo Amorín,M. Castellano,Sebastien Derriere,Andrea Comastri,Nico Cappelluti,Junxian Wang,H. C. Ferguson +21 more
TL;DR: In this article, a color deconfusion technique was proposed to search for high-z stars in the GoodS-North field using a S500{\mu}m/S24{\mu] flux density ratio.
